RECEPTACLE FOR FERMENTING- LIQUIDS.

Specification of Letters Patent.

Patented July 23,1912.

Application filed November 5, 1910. Serial No. 590,874.

To all whom it may concern:

Be it known that I, HENNING IVnNNnn- STEN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inReceptacles for Fermenting Liquids, of which the following is adescription.

My invention belongs to that general class of devices known asreceptacles, or containers, and relates particularly to a receptacle forcontaining fermenting liquids, as for example, for containing wortduring the fermentation caused by the addition of yeast, and has amongits objects the production of a simple, convenient, eflicient andsatisfactory device of the kind described for use wherever foundapplicable.

The receptacle is particularly convenient for use for home brewing.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claim.

In the drawings, wherein like reference characters indicate like orcorresponding parts, the figure is a. vertical sectional view of apreferred form of the device.

Referring to the drawings, in which the preferred form of device isshown, 1 represents the receptacle extended as at 2, to form a neck, andprovided with a closure or cover 4. The neck 2 is preferably flanged onthe exterior as at 3, to provide a part of means for securing theclosure in position, as hereafter described. Suitable packing material 5is preferably placed between the closure 4: and the neck 2, so that whenthe closure is secured or locked in place, there will be no escape ofgas or liquid between the closure and the receptacle neck. The closuremay be secured in position in any suitable manner, preferably by aplurality of eye bolts 6, each formed with an eye or head 7, andarranged on a ring 8, which encircles the neck and is prevented fromrising thereon by the flange 3. The upper ends of the eye-bolts 6 areprovided with thumb or wing nuts 13, which engage with the cooperatingextensions 14 on the closure, there being a space 15 on each extensionthrough which the eye-bolt passes.

The closure is preferably prevented from transverse displacement bymeans of the flange 16 formed thereon adapted to engage spring upon thevalve. 'provide what may be termed a tester rod opening 21vtherethrough. Any equivalent form, of valve and valve seat may beemployed.

Adjustably secured in the top of closure 4, is an adjustable member 23,which cooperates with the spring 28 and. normally maintains the valvemember 22 upon its seat.

As is obvious, turning the member 23 affords adjustment and regulatesthe pressure of the I also preferably 25, which loosely extends throughthe vent or duct 27 in the adjustable member 23, the

i rod being secured to the valve member. If

desired, the opposite end may be formed i with a ring, or otherwisearranged, so that git may be convenlently grasped to test the pressureon the valve, or to unseat the same at will. As is shown in the drawing,I preferably provide the adjustablemember 23 with an extended top'having a downwardly extending or flanged edge 28, the

closure being provided with a groove or trough 29 thereunder.

As shown in the drawing, the receptacle may be provided with a tap orfaucet 31, controlled by the usual form of valve, the handle 32 thereofbeing shown, the faucet beingconnected by a pipe 33, if not directly tothereceptacle 1. If desired, a filtering cup 34:, containing a filteringmedium 35 and strainer'36, may be employed. The receptacle is shownpositioned in an auxiliary casing or receptacle 37, having a top 38,which may contain means for cooling the contents of the receptacle 1 inwarm weather, or means for preventing the chilling or freezing of thecontents of 1 in cold weather.

The receptacle in use, assuming that it is to be used for example forthe making of beer from a suitable extract and yeast, or theirequivalents, is opened by removing the closure 4. This is done byunscrewing the thumb nuts 13 a sufficient distance, and then turning thebolts 6 down, thereby releasing the closure. It will be noted that therod the receptacle in the desired condition, after which the closure maybe positioned and locked by means of the eye-bolts 6 and thumb nuts 13.The pressure off the valve 22 on its seat may be regulated by turningthe member 23 as desired, so that when the pressure of the contents orgases within rise above a predetermined pressure, depending upon theposition of the adjustable member 23, gas will flow through the open ing21 and by the valve member 22 up through the vent 27, passing by the rod25 out to the exterior, or atmosphere. If any liquid is carried along itwill be discharged on the top of the member 23, and running over, dropoff the lip, or turned-down part 28, into the trough 29 on the closure,from which it may be removed. This construction of the member 23prevents the liquid from gathering around the outside of the member 23at the top of the closure, and thereby rusting or tending to make itditiicult to adjust the member. If at any time it is desired to test thepressure, to determine the condition of the contents of the receptacle,or unseat the valve, the rod 25 may be raised by means of the ring 26,and the escape of and liquid noted. In this way the condition of thecontents of the receptacle may be fairly accurately estimated at anydesired time.

By the use of the receptacle or outer container 37, ice may bemaintained around the receptacle 1 after the beer has been made,maintaining the same cool in summer. In other cases, where the device isto be put to other uses, suitable insulating material may be containedin the outer container 37 to protect the interior from heat or cold, asthe case may be. The arrangement of the faucet 3] extending without thereceptacle and outer casing or container 37, aiiords convenient meansfor drawing off the contents of the receptacle 1, all sediment beingprevented from passing out by means of the screen and filtering materialon the interior of the receptacle. hen the contents have been drainedoff the receptacle and parts may be cleaned and new filtering material35 be positioned in the filtering cup 84 if desired. It is of courseunderstood that any suitable means (not shown) may be employed formaintaining the pressure Within the receptacle after a portion of thecontents have been drawn oil, so that the contents will foam and nottaste flat. For illustration, an air pump suitably con nected with thereceptacle may be used for the purpose.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without departing fromthe spirit of my invention, hence I do not wish to be understood aslimiting myself to the exact form, arrangement, construction orcombination of parts herein shown and described, or uses men tioned.

lVhat I claim as new and desire to secure by Letters Patent is In adevice of the character described, a receptacle, a removable closure forsaid re ceptacle, said closure being provided with an annular channel inthe outer surface thereof and with. a projection extending up wardlvtherefrom and positioned centrally of said annular channel, saidprojection being provided with a vent opening extending centrallytherethrough and with an overhanging top, the edge of which ispositioned directly over the annular channel in the top of the closure,anda pressure actuated valve for the vent opening in said projection.

In testimony whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
